Recommended Back Loaded Horn Type Enclosure
• This example shows a ‘back
loaded horn’ type enclosure for
FE206En.
• FE206En’s magnetic circuit with
ø146mm large ferrite magnet
provides sharper resonance and
makes the unit suitable for a back
loaded horn type enclosure.
• 21mm thick plywood is used for
main section and side panels to
ensure a strong enclosure.
• Two way system using super
tweeter T90A is also recom-
mended.
